My 24" heavy barrel loves 168 gr Fed GMM, Rem Prem 168 GMM, and Southwest Ammunition 168. I had my friend's 15 year old grandson shoot in Saturday at 100 yds. First time with a bolt gun. First shot was off, I got him to hold correctly, get the cant right, and not slap the trigger and he shot the next 4 rounds in under an inch. Yours should do the same when everything is right.

There's a HUGE difference between what i assume is a heavy barreled 308win shooting 168 grain bullets and a hunting rifle (likely not a heavy barrel) in 300 winmag shooting 180 grain projectiles. His WILL NOT have the same result. I can practically guarantee it. The ammo he is running is not match ammo. I'd say a 2"group is as good as its going to get for a sporter barrel and non match/hand loaded ammo.
On a side note. Good on your grandson with that group!
